Hi Brian,

Regarding your list of gyro failures. I have the following additions/corrections from my database:
Correction: SEAWOLF the date should be 21.11.1941 not 29.11.1941.
Additions:
OSIRIS: 14.07.1941
P.34 on 25.01.1942
P.46 on 10.08.1942
P.211 on 05.10.1942
SOKOL on 02.11.1941, 21.11.1941 and 04.10.1943.
DZIK on 07.01.1944
TANTIVY on 26.10.1944

Of these three occurences had two gyro failures. So I have a total of 34 gyro failures (I may have missed some as three of yours were not in my list). Twenty-four of these were "circlers" and presented a danger to the submarine.

So I should not trust my memory! :)

Best regards,

Platon
